IMPROVEMENT IN BOTTLE-STOPPER FASTENERS.

Specification forming-part of Letters Patent No. 202,137, dated April 9, 1878; application filed February 7, 1878.

To all whom it may concern:

Be it known that I, ALBRECHT E. BAR- THEL, of Detroit, in the county of Wayne, State of Michigan, have invented an Improvement in Bottle-Stoppers, of which the following is a specification:

The nature of myinvention relates to new and useful improvements in bottle-stoppers of the class usually employed to contain liquids charged with carbonic-acid gas, where it is necessary to secure the stopper to the bottle and provide means for preventing the accidental opening of the bottle; and the invention consists in the peculiar arrangement and construction of the various parts, as more fully hereinafter set forth.

Figure 1 is a vertical section of the neck of a bottle, showing my device, partially in section, secured thereto from the front. Fig. 2 is a side elevation, showing the stopper locked in the neck of the bottle. Fig. 3 is a similar elevation, showing the stopper presented to the mouth of the bottle and ready to be locked. Fig. 4 is a modification of Fig. 1.

Like letters indicate like parts in each figure.

In the drawings, A A represent two segments of a circle each of equal length, made of strips of metal of the length required. Each of the ends of these two segments terminate in a semicircular flange, a, so that when the ends are placed together the flanges will form a circular bearing for the journals 1) of the locking-lever d. After this neck-band, made of the two equal segments A, as described, is placed around the neck, a thimble, c, is slipped over the semicircular flanges,and holds the parts together. The locking-lever dis made substantially of the form shown, pivoted at each end to the neck-band, and is provided with bearing-surfaces h h, the former beingibelow the pivotal point where the stopper-yoke k is pivoted to said locking-lever to obtain a leverage by means of which to unlock the stopper; and these flattened surfaces prevent bruising the fingers by presenting bearing-surfaces broader than the diameter of the wire of which the lever is usually made. The stopper being locked in place, a slight pressure of the fingers againstthe rear of these surfaces will readily unlock it. The other flattened bearing-surface, h, on the lever, being thrown down, forms a rest for the thumb. The stopper-yoke k is pivoted to the lockinglever, as shown, and passes through the stud lof the metallic part m of the stopper. The lower side of .this part m is provided with a T-shaped stud, a, by means of which to secure to it the rubber part t of the stopper, as shown in Figs. 1 and 4.

I am aware of the Patent'No. 158,406, issued to Charles De Quilfeldt, dated January 5, 1875, and disclaim any part of the invention therein described but device, having the flattened bearing-surfaces h h, substantially as and for the purposes set forth.
